4 Claims.

(01. Iii-# 19) Matter enclosed in Heavy brackets J appears in the original :pat-ent but :forms no part of this reissue specification; matter printed in ital-its indicates the additions niaade 'by reissue.

This invention relates to new and useful improvements -in smokersfl appliances and more particularly and specifically to a pipe attachment of which the -following is a specification.

i he primary object of this invention resides in theprovision of ;a liner insert for a pipe which extends .from the bowl bottom throughout the length of the stern, and which keeps the bowl [and stem] dry and clean at all times preventing the undesirable clogged and soggy formation whichior-ms inherently in the smoking pipe now in use.

Another object of this invention lies in the provision of such a pipe liner which 'is quickly and easily removable from a pipe to allow the replacement thereof with a clean and new liner, thereby "maintaining the bowl bottom and stem in a clean dry condition and eliminating the necessity of frequently cleaning the pipe-and thus keeping the bowl wall formations in the pipe which are fiesiralole but which are necessarily removed when a pipe is cleaned. 7

Still another object of this invention is the provision of such a pipe attachment or accessory as described which is of an extremely simple and inexpensive design and which is {cheap of] inexpensive to manufacture. H

Still further improvements and advantages will readily appear to those skilled in the art when the following description is read in the light of the accompanying drawings in which: 7

Fig. 1 is a top plan view of the improved pipe. Fig. 2 is a vertical section taken on line 2--2 of Fig. 1.

Fig. 3 is a vertical section taken on line 33 of Fig. 1.

Referring now to the accompanying drawings which illustrate the preferred embodiment of this invention. A designates a smokers pipe comprising the conventional elongated hollow stem and an integrally formed bowl 2 opening into said stem from the bottom thereof. The stem may extend to a mouthpiece 3, the stem 1 and mouthpiece 3 constituting an extension from the bowl 2.

The bowl 2 is provided with a tobacco receiving chamber formed with a recess [3] 4 in the bottom thereof, and formed as a continuation of the passageway of the stem 1, the recess [3] 4 being preferably rectangular in transverse cross section below the chamber. 5:, said} The recess [extending] also preferably extends as a slot 5 through the front wall of the bowl, the upper surface of the wall of the opening or slot 5 being flat. The surfaces 6 at the b ttom of the bowl at cach side of the recess =4 are flat, "as shown. in Fig. 3.

An elongated, preferably tapered, hollow tube r liner "B or rectangular cross section correspan-ding to ma j; the recess 4 for at Zeast't'h length "or the recess 4 through the [recess -31 slot 5 and extends beneath the bowl 'bottoin throughout the "length "of the recess, the portion 'of the hollow tube disposed in the recess its] '4 having [its] a wide, fl'at upper surface 7 ilush with the hat surf-ac' cs it an the bottom of the tobacco receiving chamber. II, where it is formed with ajl A plurality of o enines "or apertures 8 [t which] carten'd through the upper turface '7 to establish communication between the tobacco receiving chamber and the interior of the tube, uni; thereby perma smoke to be drawn through the stem from the tobacco chamber. Ks shown, the from normally larger and {9 "of the tube B is "closed and also may eaten-a I'extehd's] through the substantial distance beyon'd'the outer surface he bowl *2 The opposite and normally-surmised it bra-1e tape B is open [at a] adjacent to the mouthpiece to] or the stem so that smoke may be drawn therethro'ugh [,While the larger one "5 or the tube is closed] .ij'rhu's "it may be seen "that a complete line:- has been provided 'foithe pipe stem which "Separrates the stem from the bowl thus preventin the Tomi-"anon or soggy accumulation in the stem,

" "it the passage cf s'moke thereinto I ed'o 'eninstl when "it s desirabl to remove the liner tube is the extended end [51 9 thereof is "grasped and the liner pulled completely free of the remaining parts of the pipe, and a, new liner may then be inserted thus maintaining a dry clean stem and bowl bottom without necessitating any cleaning of the pipe. The liner B may be made of any suitable material, such as metal, plastic or the like, while the stem 1 and bowl 2 may be made of conventional materials for smokers pipes. It has been found that the upper surface 7 of the liner remains clean and free of soggy tobacco accumulation, when the ashes and residue are knocked fr m the pipe, particularly when the liner is made of a metal such as aluminum. There may, however, be a liquid accumulation within the liner, which is discarded with the liner when the latter is replaced by a new liner.

I wish it to be understood that I contemplate any modifications of the illustrated invention such as size, materials used, and general characteristics which fall within the scope of the appended [claim] claims.

Having thus described the construction and function of this invention what I desire to claim in Letters Patent is:

1. In a smoking pipe, a pipe bowl defining a bowl chamber, a pipe stem having a passageway formed longitudinally through the center thereof, formed integral with the bowl, said bowl having a recess rectangular in transverse cross section formed in the bottom of the bowl below the bottom of the bowl chamber, and providing a continuation of the passageway of the stem, a tubular member rectangular in transverse cross section providing a wide fiat upper surface, fitted within the recess of the bowl and in the passageway of the pipe stem, the upper surface of said tubular member within the bowl being flush with the surface defining the bottom of the bowl chamber, the wide flat upper surface of the tubular member having rows of openings therein, through which smoke is drawn into the tubular member from the bowl chamber.

2. In a smoking pipe, a bowl having walls and a bottom defining a chamber for receiving tobacco and the like; a stem extending rearwardly from the lower rear end of said bowl and having a longitudinally extending passage, said bowl having a recess in the bottom thereof below said chamber and formed as a continuation of said stem passage andthe surface of the bottom of said bowl chamber being flat at each side of said recess, said bowl also having an outer wall thereof provided with an opening and the upper surface of the wall of said opening being flat, said opening forming a continuation of said recess; and a hollow liner fitting within the recess of said bowl and extending into said stem passage and into said opening, said liner having a flat upper surface flush with said flat surfaces in said chamber bottom and a plurality of apertures extending through said upper surface into the interior of said liner, and the front end of said liner being closed and said liner closing said opening with the upper surface of said liner at said opening being flat to correspond with the flat upper surface of said opening.

3. In a smoking pipe, a bowl having walls and a bottom defining a chamber for receiving tobacco and the like; a stem extending rearwardly from the lower rear end of said bowl and having a longitudinally extending passage, said bowl having a recess in the bottom thereof below said chamber and formed as a continuation of said step passage, said recess being rectangular in transverse section and the surface of the bottom of said bowl chamber being flat at each side of said recess; and a hollow liner fitting within the recess of said bowl and extending into said stem passage, said liner being rectangular in cross section at least within said recess and having a flat upper surface flush with said flat surfaces in said chamber bottom and a plurality of apertures extending through said upper surface into the interior of said liner.

4. In a smoking pipe, a bowl having walls and a bottom defining a chamber for receiving tobacco and the like; a stem extending rearwardly from the lower rear end of said bowl and having a longitudinally extending passage, said bowl having a recess in the bottom thereof below said chamber and formed as a continuation of said stem passage and the surface of the bottom of said bowl chamber being flat at each side of said recess, said bowl also having an outer wall thereof provided with an opening and the upper surface of the wall of said opening being flat, said opening forming a continuation of said recess; and a hollow liner fitting within the recess of said bowl and extending irito said stem passage and through said opening to a point forwardly of said bowl, said liner having a flat upper surface flush with said flat surfaces in said chamber bottom and a plurality of apertures extending through said upper surface into the interior of said liner, the front end of said liner being closed and closing said opening with the upper surface of said liner at said opening being flat to correspond with the flat upper surface of said opening, said liner being tapered from front to rear and said opening, bowl recess and stem passage being shaped corresponding to said liner.
